You apply for the MOE waiver via and with the assistance of the International School you wish to use. You may succeed. We did about 4 years ago but then shifted our daughter to a local school as the international school was failing her academically.

Thank you both for the kind replies. I will check it out. I have intentions of returning to SG due to my unforeseen medical issues. Both of my children have been on an International School system since legal schooling age. I felt bad that due to my own medical issue, they would have to be yanked out of their school to an unfamiliar environment as well as to a total different country altogether! As a parent, I can only hope to make their transition as smooth as possible!

Spider - in the application you need to be pretty clear as to why your children should be in the FSS. Most commonly accepted reason is that you intend to migrate/leave Singapore. Second most common reason is that your children have not been in the Singapore system at all and will struggle academically.... I think the latter one will work for you. (Third reason is your child needs support or academics not found in the local system ala LKY nephew).

The admissions officer should be able to guide you on this if they are at all competent.
